The Northwestern Bulgarian dialects are two closely related dialects of the Bulgarian language, which are located west of the yat boundary and thus are part of the Western Bulgarian dialects. The range of the dialects includes most of northwestern Bulgaria, to the west of the line between Nikopol, Pleven and Mezdra and to the north of the line between Vratsa and Belogradchik. They bear strong resemblance to their neighbouring Eastern Bulgarian dialects and with some exceptions, mainly the pronunciation of yat, have the same phonological and morphological features as the neighbouring subdialects of the Eastern Bulgarian Central Balkan dialect.
The Central Balkan dialect is a Bulgarian dialect that is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes most of north-central Bulgaria, as well as the regions of Karlovo, Kazanlak and Plovdiv in southern Bulgaria, all the way down to the northernmost ridges of the Rhodopes. As a result of the mass population movements that affected eastern Bulgaria during the 19th and the beginning of the 20th century, the Central Balkan dialect is now spoken also in vast areas of northeastern Bulgaria. The most significant feature of the dialect is the pronunciation of Old Church Slavonic ѣ (yat) as or, depending on the character of the following syllable. The Central Balkan dialect lies at the foundation of formal Bulgarian. However, it is not identical to the standard language because many of its features derive from the Western Bulgarian dialects, including the Macedonian dialects, or are a compromise between Eastern and Western standard. The Central Balkan dialect includes a number of subdialects, e.g. Troyan, Lovech, Gabrovo, Karlovo, Kalofer, Tryavna, etc. which share many common features and yet have some differences.
The Subbalkan dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes the northeastern part of Bulgarian Thrace, i.e. the regions of Burgas, Sliven, Yambol, Stara Zagora and Chirpan. As a result of the mass population movements that affected eastern Bulgaria during the 19th and the beginning of the 20th century, speakers of the Subbalkan dialect have moved en masse to northeastern Bulgaria and now form a vast portion of the population of the districts of Varna, Dobrich and Balchik. Some of these also went as far as Bessarabia establishing numerous colonies there. Nowadays, a large part of the Bessarabian Bulgarians speak this dialect. The most significant feature of the Subbalkan dialect, as in all Balkan dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as or, depending on the character of the following syllable.
The Pirdop dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. Its range includes the towns of Pirdop, Zlatitsa and Koprivshtitsa, as well as several neighbouring villages. The most significant feature of the dialect, as in all Balkan dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as or, depending on the character of the following syllable. However, the Pirdop dialect also features a number of characteristics which bring it closer to the neighbouring Western Bulgarian dialects, and especially to the Botevgrad dialect and which, in turn, separate it from the rest of the Balkan dialects.
The Rup dialects, or the Southeastern dialects, are a group of Bulgarian dialects located east of the yat boundary, thus being part of the Eastern Bulgarian dialects. The range of the Rup dialects includes the southern part of Thrace, i.e. Strandzha, the region of Haskovo, the Rhodopes and the eastern half of Pirin Macedonia.
The Smolyan dialect or Central Rhodope dialect is a Bulgarian dialect of the Rhodopean group of the Rup dialects. Its range includes most of the Central Rhodopes, i.e. the region of Smolyan. Its immediate neighbours are the Rhodopean Hvoyna dialect to the north, the Serres-Nevrokop dialect and the Razlog dialect to the west and the Turkish dialects of the Turkish population in the Eastern Rhodopes. To the south, the Smolyan dialect crosses the Greek-Bulgarian border and is spoken by much of the Muslim Bulgarian (Pomak) population in Western Thrace. As a result of the rugged mountainous terrain and the century-long isolation of the region from the rest of the country, the Smolyan dialect is the most idiosyncratic of all Bulgarian dialects and is not readily understandable even for its immediate neighbours.
The Chepino dialect is a Bulgarian dialect of the Rhodopean group of the Rup dialects. Its range includes the northwestern Rhodopes, i.e. the towns of Velingrad, Rakitovo and Kostandovo and the villages of Dragichevo and Dorkovo. Its immediate neighbours are the Central Balkan dialect and the Ihtiman dialect to the north, the Babyak dialect to the west and south and the Hvoyna dialect to the east. The Chepino dialect is spoken by both Orthodox and Muslim Bulgarians in the region irrespective of religious affiliation.
The Zlatograd dialect is a Bulgarian dialect, member of the Rup or Southeastern Bulgarian dialects. The Zlatograd dialect is spoken in the southwestern part of the Eastern Rhodopes, i.e. in the town of Zlatograd, as well as a number of neighbouring villages and towns, e.g. Nedelino, Kirkovo, etc. The Zlatograd dialect is most closely related to the eastern and western Rup dialects, but also shares a number of phonological and morphological characteristics with the Rhodopean dialects. Thus, it is usually considered to be transitional between the two groups.
The Babyak dialect is a Bulgarian dialect, member of the Rup or Southeastern Bulgarian dialects. It is spoken in several mountainous villages on the western fringes of the Rhodopes and is thus sandwiched between the Chepino dialect on the east and northeast and the Razlog dialect to the south and west. It shares a number of phonological characteristics with both the Rup and the Southwestern dialects. Because of its specific reflexes of Old Church Slavonic yat, it is generally classified as a Rup dialect but is actually transitional between the two dialectal groups.
The Razlog dialect is a Bulgarian dialect, member of the Rup dialects. Its range includes the valley of Razlog in southwestern Bulgaria and its immediate neighbours are the Rup Serres-Nevrokop dialect to the south, the Babyak dialect to the east, the Samokov and Ihtiman dialects to the north and the Blagoevgrad-Petrich dialect to the west. It shares a number of phonological characteristics with both the Rup and the Southwestern dialects.
The Teteven dialect is a Bulgarian dialect, which is part of the Balkan group of the Eastern Bulgarian dialects. It is spoken in the town of Teteven and several neighbouring villages and is almost completely surrounded by the Central Balkan dialect, except on the west where it borders on the Western Bulgarian Botevgrad dialect. The most significant feature of the dialect, as in all Balkan dialects, is the pronunciation of Old Church Slavonic ѣ (yat) as or, depending on the character of the following syllable.
The Southwestern Bulgarian dialects are a group of Bulgarian dialects which are located west of the yat boundary and are part of the Western Bulgarian dialects. The range of the Southwestern dialects on the territory of Bulgaria includes most of west central and southwestern Bulgaria. The Southwestern dialects border on the Northwestern dialects to the north, the Transitional dialects to the northwest and the Balkan dialects and the Rup dialects to the northeast and southeast, respectively. If the Macedonian language is regarded as a third literary form of Modern Bulgarian, then the Southwestern dialects extend west and southwest to include the Slavic dialects in Vardar Macedonia and the western half of Greek Macedonia. Should the Macedonian language be counted as a separate language, then the southernmost dialect of the group, the Blagoevgrad-Petrich or Pirin dialect, along with the corresponding variety on the Macedonian side of the border, the Maleshevo dialect, constitute a transitional dialect between Bulgarian and Macedonian. A defining characteristic of the Southwestern dialects is the gradual transition from one dialect to another, as well as to dialects which belong to other dialectal groups. For example, the Dupnitsa dialect is transitional to both the Samokov dialect and the Blagoevgrad-Petrich dialect, the Botevgrad dialect is transitional to the Eastern Bulgarian Balkan dialects, and especially to the Pirdop dialect, etc. etc.
The Vratsa dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Vratsa in northwestern Bulgaria. The Vratsa dialect borders on the transitional Belogradchik dialect to the west, the Northwestern Byala Slatina-Pleven dialect to the north and east, the Botevgrad dialect to the southeast and the Sofia dialect to the south.
The Botevgrad dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Botevgrad and Etropole in northwestern Bulgaria. It is located on the yat boundary and is closely related to the Eastern Bulgarian Pirdop dialect.
The Ihtiman dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the regions of Ihtiman, Kostenets and Septemvri in central western Bulgaria. It is transitional between the Botevgrad and Samokov dialect.
The Elin Pelin dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the eastern part of the Sofia valley in central western Bulgaria. Its immediate neighbours are the Vratsa dialect to the north, the Botevgrad dialect to the east, the Sofia dialect to the west and the Samokov dialect to the south.
The Sofia dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in western part of the Sofia valley by part of the Shopi. Its immediate neighbours are the Vratsa dialect to the north, the Elin Pelin dialect to the east, the Transitional dialects to the west and the Samokov dialect to the south.
The Samokov dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Samokov in central western Bulgaria. Its immediate neighbours are the Sofia dialect and Elin Pelin dialect to the north, the Ihtiman dialect to the east, the Dupnitsa dialect to the west and the Razlog dialect to the south.
The Kyustendil dialect is a Bulgarian dialect, member of the Southwestern Bulgarian dialects, which is spoken in the region of Kyustendil in central western Bulgaria. It borders on the Transitional dialects to the north, the Dupnitsa dialect to the east and the Blagoevgrad-Petrich dialect to the south. It is closely related to the Dupnitsa dialect.
The Breznik dialect is a Bulgarian dialect, member of the Transitional dialects, which is spoken in the region of Graovo in central western Bulgaria. It borders on the Tran dialect to the west and north, the Kyustendil dialect to the south and the Sofia dialect to the northeast and features characteristics typical for the Southwestern Bulgarian dialects.
